I have a couple thoughts on this, however I have to acknowledge that i did not live through this experience myself.
I remember reading through a similar thread a while back, it may have been on a different forum. Incontinencesupport.org i think or something like that. Well anyways there was a young man who was currently attending college, if i remember right he reported having bother bowel and bladder incontinence his entire life. He describing going into college with confidence in the fact that he had to wear diapers. He stated that he had accidents in front of other people, referenced changing his diaper and even played football with his diaper showing. What he stated was that no one seemed to care. They were accepting and just went along with it.
My own experience of college was drastically different then high school as well. I didn't have these issues then. But in High school i was bullied. Junior high and high school were miserable for me. I have mild cerebral palsy and was a little socially delayed, so in other words i had a target on my back.
College was a completely different world. The first thing i noticed was open and accepting people were about everything. Everyone was focused on people treating each other respectfully and kindly, and people who would engage in bullying behavior tended to be ostracized by the group as a whole. No one seemed to be targeting anyone. I did go to a smaller school, where there was only one dorm of about 100 people. I was on friendly terms with all of them.
I can't guarantee that you will have the same experience, but i am guessing that you find that people are more accepting and supportive then you would think.
